Feature Comparison
How eSentire and LevelBlue stack up across key capabilities.
Threat Intelligence
LevelBlue leads
eSentire Curates threat intelligence from multiple commercial and open-source feeds, enriched by findings from its own 24/7 threat hunting operations. Intelligence is tightly integrated into detection logic for real-time application.
LevelBlue AT&T-backed threat intelligence with visibility into one of the world's largest network backbones. Alien Labs research team produces proprietary intelligence, and the Open Threat Exchange (OTX) community contributes additional context at massive scale.
Detection Speed
eSentire leads eSentire Industry-leading response times with a mean time to contain under 15 minutes. Detection pipeline is engineered to minimize latency from alert to analyst action to threat containment.
LevelBlue Solid detection capabilities powered by USM Anywhere correlation and Alien Labs intelligence. Detection is effective but optimized more for breadth and accuracy across large environments than for raw containment speed.
Platform & Technology
Even match eSentire Proprietary MDR platform built specifically for detection and response workflows. Technology stack is focused, with clear visibility into what is being monitored and how threats are being handled.
LevelBlue USM Anywhere provides unified asset discovery, vulnerability assessment, intrusion detection, behavioral monitoring, and SIEM in a single platform. Broad functionality, though the consolidated approach can add complexity.
Scale & Coverage
LevelBlue leads eSentire Scales well for mid-market and upper mid-market organizations. Coverage spans endpoints, cloud, and network, though the primary focus remains on environments where speed and signal quality matter most.
LevelBlue Built for enterprise-scale deployments with global coverage. AT&T infrastructure heritage means LevelBlue can handle complex, distributed environments with thousands of assets across multiple geographies.
Incident Response
eSentire leads eSentire Incident response is embedded in the MDR service. Analysts take direct containment actions on behalf of the customer when threats are confirmed, reducing the gap between detection and remediation.
LevelBlue Incident response capabilities are available, though they may be scoped as a separate service tier. The focus is on alerting and guided response, with direct containment actions depending on the engagement model.
Reporting & Visibility
eSentire leads eSentire Transparent reporting with clear metrics on threats detected, actions taken, and mean time to respond. Customers get direct visibility into SOC operations and can see exactly what analysts are doing.
LevelBlue Comprehensive reporting through the USM Anywhere dashboard, including compliance-oriented views and executive summaries. Reporting is thorough but can be dense given the breadth of data collected.
Pricing & Value
Even match eSentire Pricing is competitive for mid-market organizations and structured around the scope of MDR coverage. Transparent pricing with fewer hidden costs, making budgeting predictable.
LevelBlue Enterprise pricing reflects the breadth of the platform and the scale of AT&T-backed infrastructure. Can be cost-effective for large organizations already in the AT&T ecosystem, but may be expensive for smaller deployments.
Pros & Cons
eSentire
Strengths
- Fastest mean time to contain in the MDR market, with sub-15-minute response benchmarks
- Transparent operations that give customers clear visibility into SOC activity and decision-making
- Agile, focused MDR engagement without the complexity of a multi-service platform
- Incident response included in the core MDR service, not billed separately
- Strong fit for mid-market organizations that want dedicated MDR without enterprise overhead
Limitations
- Smaller threat intelligence footprint compared to providers with global network backbone visibility
- Less suited for very large, complex enterprise environments with tens of thousands of assets
- Does not offer a unified security management platform covering SIEM, vulnerability scanning, and asset discovery
- Limited brand recognition compared to AT&T-backed alternatives, which may matter in enterprise procurement
Best For
eSentire is best for mid-market organizations and growing enterprises that prioritize speed of response, operational transparency, and a focused MDR engagement. It is ideal for companies that want a dedicated detection and response partner without the overhead of managing a broad unified security platform, and that value fast containment times over the breadth of a full SIEM and vulnerability management stack.
LevelBlue
Strengths
- AT&T-backed threat intelligence with unmatched global network visibility and Alien Labs research
- USM Anywhere provides a unified platform covering SIEM, vulnerability assessment, and intrusion detection
- Built for enterprise scale with infrastructure to support complex, globally distributed environments
- Open Threat Exchange (OTX) community enriches detection with crowd-sourced threat data
- Strong fit for organizations already operating within the AT&T or LevelBlue ecosystem
Limitations
- Detection-to-containment speed may lag behind dedicated MDR specialists focused solely on response
- Platform complexity can create a steeper learning curve for customer-side teams
- Enterprise pricing may be prohibitive for mid-market organizations with smaller security budgets
- Incident response may require a separate engagement or service tier depending on the contract structure
Best For
LevelBlue is best for large enterprises with complex, distributed IT environments that need a unified security platform backed by world-class threat intelligence. It is a natural fit for organizations that benefit from AT&T's global network visibility, need a single platform for SIEM, vulnerability assessment, and MDR, and have the budget and internal resources to take full advantage of the platform's capabilities.
